Black Lake.

After a long walk they arrived in a small secluded spot next to the lake.

"Perfect." Luna smiled and began unbuttoning her shirt.

"Luna? What are you doing?"

"We can't swim in our clothes." The blonde explained as she dropped her skirt revealing her smooth pussy.

Then she jumped into the water. She came up and waved to Hermione.

"Come on!"

Hermione didn't think it was a good idea. What if someone came by and saw them? But she still found herself taking off her shirt.

Once she was completely nude she slowly began sinking into the water.

"Luna it's freezing!"

"So? It helps my hot pussy." Luna smiled and back stroked some.

Hermione bit her lip as she came up the her shoulders in the cold water.

"There isn't that better?" Luna pattled over.

"It's bloody cold." Hermione said through clenched teeth.

"Let me warm you."

Next thing Hermione knew she was felt Luna's nude body against hers. The Luna kissed her deeply as her hands came to her ass.

Before long both were snogging each other as the floated in the lake.
